Abstract
Description
- The present invention relates to cosmetic preparations with an active substance combination of hyaluronic acid and saponins.
- The desire to appear beautiful and attractive is naturally rooted in man. Even if the beauty ideal has undergone changes over the course of time, the desire for a flawless outward appearance has always been the aim of human beings. The condition and the appearance of the skin is a significant part of a beautiful and attractive outward appearance. Regular cleansing and care are necessary to give the skin a flawless appearance.
- Nowadays, consumers are offered a large number of cosmetic preparations for skin care, generally in the form of creams and lotions, i.e., as an emulsion. Products that temporarily or permanently delay or remove signs of aging in the skin (in particular the development of fine lines and wrinkles) thereby have steadily increasing importance. In addition to water for moisturizing the skin and oils and lipids for regreasing the skin, skin care products of this type contain a plurality of active substances, auxiliaries and additives.
- The “aging skin” of older people differs from the “normal skin” of younger people in a plurality of symptoms. It is generally drier and shows an uneven hornification. Through its lack of water-binding capacity in the corium, deep wrinkles develop. The tendency of the epidermis to form vesicular flaking is increased. The appearance of old skin develops in genetic aging as with chronic environmental damage, as is caused, e.g., by excessive UV exposure.
- Exogenous factors, such as UV light and chemical noxae, can have a cumulative effect and, e.g., accelerate or supplement the endogenous aging processes. In the epidermis and dermis, for example, the following structural damage and functional disorders appear in the skin as a result of exogenous factors:
- a) Visible telangiectasis (cuperosis);
- b) Flaccidity and the development of wrinkles;
- c) Local hyperpigmentation, hypopigmentation and defective pigmentation (e.g., age spots);
- d) Increased susceptibility to mechanical stress (e.g., cracking)
- e) Decrease in the collagen content of the skin (e.g., through reduced new synthesis and/or through increased decomposition)
- f) Disturbances in the glycosaminoglycan and elastin metabolism.
- Over the past years skin research has developed or discovered a large number of active substances with which skin aging manifestations can be cosmetically treated and the visually perceptible skin aging process can be slowed down.
- Conventional skin care products for the prophylaxis and treatment of skin aging symptoms, however, have the disadvantage that these active substances as a rule can be incorporated into cosmetic formulations only with difficulty and in unsatisfactory amounts. Furthermore, according to the prior art the disadvantage regularly occurs that combinations of active substances are difficult to incorporate into the preparations, since the active substances can exhibit incompatibility not only with the “carrier preparation” but also among one another.
- The object of the present invention was to develop a new, stable and cosmetically effective skin care preparation for the prophylaxis and treatment of skin aging manifestations, in particular fine lines and wrinkles. In particular the skin's moisture should be increased by the skin care preparation.
- The objects were surprisingly attained through a cosmetic preparation containing a combination of active substances of
- 0.001 to 3% by weight of hyaluronic acid and
0.01 to 4% by weight of saponins,
the weight data being based on the total weight of the preparation. - Furthermore, the objects were surprisingly achieved through a cosmetic preparation containing a combination of
- 0.001 to 3% by weight of hyaluronic acid and
0.01 to 8% by weight of leguminose extract, which contains 0.01 to 99% by weight of saponins,
the weight data of the hyaluronic acid and the leguminose extract being based on the total weight of the preparation and the weight data of the saponins being based on the total weight of the leguminose extract. - In particular, the objects are surprisingly attained through a cosmetic preparation containing a combination of
- 0.001 to 3% by weight of hyaluronic acid and
0.01 to 8% by weight of soy extract, which contains 0.01 to 99% by weight of saponins,
the weight data for the hyaluronic acid and the soy extract being based on the total weight of the preparation and the weight data for the saponins being based on the total weight of the soy extract - It has proven to be particularly advantageous according to the invention thereby, if the weight ratio of hyaluronic acid to saponins is from 1:1 to 1:10.
- Advantageous embodiments of the invention are characterized in that the preparation contains saponins from glycosides of triterpene sapogenins in addition to optionally further saponins from glycosides of steroid sapogenins.
- Hyaluronic acid is a glycosaminoglycan occurring in the vitreous body of the eye, the synovial fluid of the joints and in the skin, which together with chrondroitin sulfates and dermatan sulfate is a constituent of all connective tissue (apart from cornea).
- Hyaluronic acid is a high molecular weight compound with MR between 50,000 and several million. The basic unit of hyaluronic acid is an aminodisaccharide constituted by D-gluconic acid and N-acetyl-D-glucosamine in β-(1→3)-glycosidic bonding, which is β-(1→4)-glycosidically linked to the next unit:
- The sodium salt of the hyaluronic acid is used as moisturizer for the production of cosmetic agents (Römpp online Lexikon Version 2.5, 2004).
- Saponin (from the Latin “sapo” for soap) is used to designate a group of generally vegetable glycosides that as surface-active compounds form colloidal saponaceous solutions.
- Saponins are subdivided according to the type of their aglykones, the sapongenins, into triterpene saponins and steroid saponins. The carbohydrate content can consist of up to 11 monosaccharide radicals (mostly D-glucose, D-galactose, L-rhamnose, L-arabinose, D-xylose, D-fucose, D-glucuronic acid).
- The most important saponins occurring in foodstuffs, the oleanoic acid saponins (beetroot), glycyrrhizine (licorice root) and the soybean saponins belong to the family of triterpene-saponins.
- In cosmetics, saponins are used as humectants and dispersing agents or foaming agents with tooth powders, mouth-washes and shampoos (Römpp online Lexikon Version 2.5, 2004).
- Although the active substances according to the invention are known to one skilled in the art in the field of cosmetics, it has not been possible hitherto to incorporate the combination of hyaluronic acid and saponins into cosmetic preparations, in particular emulsions, in a stable manner and effective form. For instance, according to the prior art the problem always arose with the combination of the two active substances that the homogeneous incorporation of the two raw materials was not possible according to a standard method. It was thus not possible either to guarantee a constant active substance concentration, particularly over a longer period. Both raw materials cannot be incorporated via the lipid phase, since they contain hydrophilic molecular constituents. But incorporation of the two raw materials via the aqueous phase is not possible either, since the saponins and hyaluronic acid cannot be homogeneously dissolved/dispersed in the aqueous phase simultaneously without forming cloudiness/crystals.
- It was now possible to solve the problem according to the invention by developing a special method for producing a cosmetic preparation containing saponins as well as hyaluronic acid: the saponins or the plant extract containing the saponins is hereby first mixed with at least four times the quantity of a glycol with a log P value between −3.6 and 1 and dissolved with constant stirring and heating. Subsequently the solution is added to the pre-emulsion that is still warm if possible. Alternatively, the saponin can also be incorporated into the aqueous phase of the preparation, which contains at least four times the saponin quantity of corresponding glycol: while being heated and stirred constantly, the poorly soluble substance is stirred in and dispersed and subsequently combined with the fat phase, which contains the emulsifiers. It proved advantageous in both cases to stir and pre-swell the hyaluronic acid separately in a multiple quantity of water, so that a gel is formed. This is added to the emulsion, which is no longer very hot, while being stirred.
- Within the scope of the present invention, the preparations according to the invention per se and the preparations produced according to the method according to the invention and the preparations used according to the invention are understood to be in accordance with the invention or preparations according to the invention.
- It is advantageous according to the invention if the preparation according to the invention contains saponins based on triterpene sapogenines. In the use of soy saponin, these are in particular saponins from soy sapogenol A or soy sapogenol B. However, optionally saponins on the basis of steroid sapogenines can also be contained.
- The leguminose extracts (fabaceae fam.) are preferably selected from representatives of the genera abrus, anagyris, andira, anthyllis, arachis, aspalathus, astragalus, baptistia, canavalia, castanospermum, cicer, crotalaria, cyamopsis, cytisus, derris, dipteryx, galega, genista, glycine, glycyrrhiza, gymnoclamdus, indigofera, laburnum, lathyrus, lens, lespedeza, medicago, melilotus, mucuna, myroxylon, ononis, oxytropis, phaseolus, physostigma, piptadenia, psicidia, pisum, pterocarpus, robinia, sophora, trifolium, trigonella, ulex, vigna, vicia and wisteria.
